1.4.1 Overview of VSP
The HP-UX host on which the vPars and Integrity VM V6 product is installed is called VSP. The VSP
manages the physical resources such as processor cores, memory, and IO devices on the system.
The VSP has AVIO sub-systems running for Storage and Network IO. The AVIO sub-systems run
on top of physical NIC and HBA instances.
The VSP is the manageability platform from where the vPars and VM guests are created, modified,
booted, shutdown, or removed. The VSP provides a set of CLI options and GUI Management tools
for administering and monitoring the vPars and Integrity VM instances.
The VSP is a specialized HP-UX host which is optimized to provide maximum system performance
for vPars and Integrity VM guest instances, hence DO NOT run any type of resource intensive
applications on the VSP. For more details about applications that can and must not be run on VSP,
see Section 3.7 (page 41).
For more information about VSP configuration, see Chapter 3 (page 37).
